Well you're obviously just trolling so I won't even bother after this but on the off chance you're genuine, consider this:
The story of the hero, the monster, and the princess has been around since the earliest recorded human civilizations.
Now, despite your assertions, people aren't stupid. They know what they like. If they don't like something the do something about it. If they don't like a story they won't tell it anymore.
Ergo, by virtue of this archetype having lasted this long, perhaps that means there's something to this tale. That maybe people enjoy it. That while they might also (and most assuredly do in the right conditions) enjoy subversions to this model they also enjoy it when it's played straight.
The story isn't broken. There's nothing wrong with the model. If there was, it wouldn't have lasted this long.
A true subversion, in any case, would involve Finn telling the Princess and all of Ooo to screw off and have him sail away, or join up with the villain. Not necessarily good, but at least it'd be something.
Bubblegum's early hints at totalitarianism were a good start but it fell apart when they started to justify it and not have Finn call her out on it or attempt to stop her.
